Product Description

Single-Spring Mechanical Seal 301 Replace Aesseal B01 Burgmann Bt-Ar


Operations Conditions OF Water Pump Shaft Seal​ :


  1. Rubber bellows mechanical seal
  2. Unbalanced
  3. Single spring
  4. Independent of direction of rotation
  5. Short axial installation length
  6. Shaft diameter: d1 = 6 … 70 mm (0.24" … 2.76")
  7. Pressure: p1* = 6 bar (87 PSI),
  8. vacuum … 0.5 bar (7.45 PSI) up to 1 bar (14.5 PSI) with seat locking
  9. Temperature:
  10. t* = -20 °C … +120 °C (-4 °F … +248 °F)
  11. Sliding velocity: vg = 10 m/s (33 ft/s

Mechanical seal for large-series cold water pumps, produced in millions of units per year. The BT-AR owes its success to the wide range of application, the short axial length (this allows for more economic pump construction and saves material), and the best quality/price ratio. The elasticity of the bellows design enables a more robust operation.

The BT-AR can also be used as a multiple seal in tandem or back-to-back arrangement when the product media cannot ensure lubrication, or when sealing media with a higher solids content. Installation proposals can be provided upon request.
